Ancient DRS

ACAF1 aerodynamics were pretty much in their infancy in 1969. When the huge wings mounted on struts were outlawed earlier in the year, engineers attempted to innovate by other creative means, like the asymmetric rear spoiler on Chris Amon's Ferrari 312 seen here at Silverstone. It was something of an ancestor to the current DRS system, although a fixed profile version. There's no stopping progress !
